Case series of six kidney transplanted patients with COVID‐19 pneumonia treated with tocilizumab
Abstract
Few reports described the outcome of kidney transplanted patients (KTs) affected by COVID‐19 treated with interleukin‐6 receptor inhibitor tocilizumab (TCZ). We report our case series of 6 KTs with COVID‐19 pneumonia who received TCZ: All were of male gender, with a mean age of 55.5 ± 8.4 years, a median time from transplantation of 3611 days (1465‐5757); 5/6 had cardiovascular comorbidities, 1/6 had diabetes, and 3/6 have one or more previous KTs. Four out of six patients died, at an average time of 9.75 ± 2.4 days after tocilizumab administration, 3/6 due to a coexistent septic shock. Two patients improved after TCZ and were discharged at 20 and 21 days, respectively; in both patient, a significant increase of total lymphocyte count was observed. In conclusion, KTs, where the role of peculiar factors such as chronic immunosuppression is still undetermined, represent a high‐risk group with significant COVID‐19‐associated mortality. The evaluation of the TCZ effect in COVID‐19 pneumonia requires controlled studies (ideally RCTs) in this specific population.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
